Last night I was driving along slowly off an island and it made a noise like a tyre going down really fast, but it wasn't, it lasted a couple of seconds. I have checked all the hoses etc and can't see anything obvious. It drives and boosts normal and the aircon is ice cold. The car is a MY01 WRX. Just wondering if anyone has had any similar problems or knows what this could be. Thanks in advance.

 

if everything is normal, then theres no problem....
